PROGRAMMING THE STEERING WHEEL ANGLE SENSOR
NOTESSpecial notes:
–The status is declared as correct when it is STATUS 4 (nominal mode). Otherwise,
apply this fault finding procedure.
–An unprogrammed steering wheel angle sensor will cause the Service warning light
to come on.
–If the steering wheel angle sensor has never been programmed, the Service warning
light will flash rapidly until the index position is detected.
VARIOUS POSSIBLE STATUS VALUES (with the meaning):
STATUS 1–Steering wheel index not detected.
–Straight ahead wheel position not programmed.
–Invalid angle value.
–NOT PROGRAMMED: Program the steering wheel angle sensor.
STATUS 2–Steering wheel index detected.
–Straight ahead wheel position not programmed.
–Invalid angle value.
–NOT PROGRAMMED: Program the steering wheel angle sensor.
STATUS 3–Steering wheel index not detected.
–Straight ahead wheel position not programmed.
–Invalid angle value.
–PROGRAMMING DONE, CONFIRM ANGLE: Turn the steering wheel to right full lock, and then
left full lock; then slowly return to the centre point and go slightly beyond.
STATUS 4–Straight ahead wheel position not programmed.
–Valid angle value.
–PROGRAMMING COMPLETE
Note:
A present or stored fault may prevent the change to STATUS 4.
AFTER REPAIRRun a system fault check.
Repeat the conformity check.

STATUS 1 OR STATUS 2
If the status is STATUS 1 or STATUS 2, program the steering wheel angle sensor (see Configurations and
programming).
STATUS 3
If the status is STATUS 3, turn the steering wheel to right full lock, and then left full lock; then slowly return to the
centre point and go slightly beyond.
Status ET020 should become STATUS 4.
Note:
A present or stored fault can impede STATUS 4 (make the necessary repairs, consulting the fault finding manual).
After the battery is disconnected, status ET020 is STATUS 3 and PR121 Steering wheel angle remains 0.
Consult the Replacement of components section for the procedure to follow after disconnecting the battery.
AFTER REPAIRRun a system fault check.
Repeat the conformity check.

ENGINE OPERATION
STOPPED

STARTING
NOTESThis signal is sent by the injection computer and is then transmitted to the electric
power-assisted steering computer via the multiplex network.
STOPPED: the engine has not yet been started or has been stopped normally, using the Start button.
STALLED: the engine is stopped, but it has been stopped abnormally, without using the Start button.
RUNNING: the engine is presently running.
STARTING: the engine is being actuated by the starter.
If the signal does not match the actual status of the engine, run a multiplex network test.
Refer to the interpretation of fault DF033 Multiplex network if necessary.
AFTER REPAIRRun a system fault check.
Repeat the conformity check.

PR003
VEHICLE SPEED
NOTESThis signal is sent by the ABS computer to the multiplex network.
The vehicle speed signal can adapt the steering assistance to the vehicle speed.
PR003 must be equal to the actual vehicle speed, within 6 mph (10 km/h).
If the parameter does not match the actual vehicle speed:
–run fault finding on the multiplex network using the diagnostic tool,
–consult the interpretation of faults DF033 Multiplex network and DF057 Vehicle speed multiplex signal.
If the fault is still present, contact the Techline.
Note:
If the vehicle speed multiplex signal is absent or invalid, the value displayed on the tool is 0 or a fixed value
(depending on the configuration).
AFTER REPAIRCarry out a road test, followed by a check with the diagnostic tool.

PR012
CURRENT ABSORBED BY THE MOTOR
NOTESNone
Parameter PR013 indicates the stipulated current setpoint for the steering motor.
This current depends:
–on the vehicle speed,
–on the torque applied to the steering wheel.
Parameter PR012 indicates the current actually consumed by the steering motor.
The value of parameter PR013 Setpoint for current absorbed by motor should be almost equal to the value of
parameter PR012 Current absorbed by motor.
If the parameters do not match the values indicated in the Conformity check, consult the interpretation of fault
DF035 Variable power assisted steering motor.
AFTER REPAIRCarry out a road test, followed by a check with the diagnostic tool.
